Halo 2 Anniversary Lag

So I have had problems with Halo 2 Anniversary before. The solution the was to get a computer that can actually run it(onboard vs dedicated graphics). Now I have a GTX 1660 Ti GPU and a Ryzen 7 4800H CPU. In H2A multiplayer, I get 144 fps on max settings, but if I try to move or look, it freezes for part of a second. I know my hardware shouldn’t be the problem, because another graphically-intensive game I have(Splitgate) runs fine. Does anyone know of anything I can change or is this a bug 343 needs to fix? I can’t seem to find anyone else with a similar problem though
